WRITING/CONSTRUCTED REPONSE ANCHOR PAPER EXEMPLARS GRADE 8 INFORMATIVE

Grade 8 WRITING Section 1

Writing Topic:

Write an informational paper that examines the topic of how people learn and how they can increase their brain power. Be sure to use information from both sources in your paper.

Before you begin planning and writing your paper, read the two passages:

1. "Changing Your Mind--One Thought at a Time" 2. "Our Brain: For Better or For Worse"

Changing Your Mind--One Thought at a Time

The Plastic Brain 1 Your brain is always changing. It will continue to transform throughout

your entire life. Whether your brain changes for better or worse is up to you. This has not always been the popular belief, however. 2 Historically, it has been thought that the brain developed until a certain age and then became fixed. However, research over the last several years has shown that the brain is not rigid at all, but has the ability to be flexible, or plastic, and is able to change and learn throughout a person's lifetime. The official term for the brain's ability to grow, change, and learn is called plasticity.

Learning 3 Learning occurs when new knowledge is gained through instruction or

experience. Memory is what allows this new knowledge to be remembered over time. Knowledge and experience, however, are not all that is involved in learning. Long ago, Albert Einstein made a statement about learning that science has only recently begun to understand. Einstein said, "Imagination is more important than knowledge. Knowledge is limited." 4 Think of knowledge as a tool and imagination as the hand that uses the tool. The more tools the hand has to use, the more it can build. Using your imagination exercises your brain and increases its ability to use multiple tools for learning.

5 Some studies suggest that imagination plays a key role in memory, as well. In one study, people were asked to remember a list of words using several different strategies, imagination being one of them. Those asked to use imagination as a memory tool were told to imagine that they were acting out the word. Those that used this approach were able to better remember details than those who used other methods of recall.

A Library of Memories 6 Memory and learning go hand in hand. Understanding requires the use

of memory: to understand something you must remember it. On the other hand, when something is understood, it also becomes easier to remember. It is important to have a sense of how memory works in order to recognize how memory and learning help each other. 7 Think of the human brain as a vast library. Instead of shelf after shelf of books, this library is full of memories. The hippocampus is the part of the brain that acts as a librarian. It is responsible for deciding what to do with short-term memories. It is also in charge of organizing and storing long-term memories. If the brain decides that new information stored in short-term memory is useful, it will deposit the memory into long-term storage. In other words, the brain's librarian will permanently "shelve" the memories your mind deems important enough to remember. 8 Not only does the brain store memories in the library of the mind for the use of learning, but it constantly redesigns the physical structure and organization of the library itself, creating pathways for quicker access to "important" information.

The Ability to Think 9 Humans have the ability to be aware of their own thoughts. Although the

brain remembers information we do not always choose to remember, we can decide what information is important by being aware of our thoughts. Some scientists report that because of this, humans who pay attention to their thoughts should be able to choose which thoughts will become a part of their long-term memory. Not only can the brain decide which thoughts are worth keeping, but it can choose how it wants to organize its library. 10 The thoughts you think about most will create the dominant pathways on which the librarian of your brain will travel and build upon. Your thoughts create physical routes in your brain. The more you think a thought, the more you establish the path for that same thought to be more easily repeated. These thoughts are "stored on the shelves" of your long-term memory.

Creating Awareness 11 Although we are often unaware of the pathways being built in our brain,

the very act of being focused and purposeful about what we are thinking and learning can change the way our brain stores and uses information. In other words, we can give the libraries in our heads an upgrade by simply choosing to focus on what we want to think about. 12 How does this work? You have approximately 70,000 thoughts per day. Interestingly, many of those thoughts will be the same ones looping around again and again. The more you think "I can't do this," for example, the more likely that experience will become true for you. This is because thinking these thoughts over and over creates a route for easy access to the shelves that contain the memories of all the things you "cannot do." 13 Learning how to exercise your mind and use tools to increase learning is therefore only a part of the learning process. Do you have what it takes to improve your brainpower? The first step is to simply believe that you can.

Our Brain: For Better or For Worse

INTRODUCTION 1 The human brain has been the topic of many studies, due to advancement

in technology and medical science. Scientists at the American Research Institute of Human Learning want to know what influences the brain, for better or for worse. This study looks at three different experiments conducted throughout the country. The following is a brief summary of what was learned.

EXPERIMENT 1: "What effect does exercise have on how the brain performs?" Performed at NRC Laboratories in Spokane, Washington

Subjects and Procedure 2 The study included 80 subjects (40 females and 40 males between the

ages of 30?40) of similar educational background and intelligence. The subjects were randomly assigned to Group A and Group B. There were 40 subjects in each group. Group A participated in 10 minutes of exercise on a treadmill before completing mazes of varying levels of difficulty within a given period of time. Group B did not exercise and was simply asked to complete the same mazes within the given time period.

Results and Discussion 3 Overall Group A performed better in successfully completing all levels of

the mazes. Additionally, subjects in Group A reported greater satisfaction with the ability to focus. There was a significant difference in mental performance between the two groups.

EXPERIMENT 2: "What effect does sleep have on mental function?" Performed at Sleep Research Studies in Hastings, Nebraska

Subjects and Procedure 4 The study included 20 subjects (10 females and 10 males between the

ages of 20?30) of similar educational background and intelligence. All subjects reported they were good sleepers. The subjects stayed in the lab for four nights in a row. Ten (10) subjects were assigned to Group A. They continued to sleep their normal sleep schedule. Ten (10) subjects were assigned to Group B. They were allowed less sleep each night. Each day, subjects were asked to complete mental tasks of a similar level of difficulty.

Results and Discussion 5 Subjects in Group A received average scores on the daily tasks. Subjects

in Group B scored below average. The more sleep lost by subjects in Group B, the longer it took them to complete the tasks and the less accurate their results were. Group A reported greater satisfaction with the ability to focus on the tasks. EXPERIMENT 3: "What effect does positive or negative expectation have on academic performance?" Performed at Smith College in Northampton, Maine Subjects and Procedure 6 The study included 500 subjects (250 females and 250 males between the ages of 17?19) entering their freshman year of college. Based on their high school grades and college entrance exams, the college used a formula to predict what each student's first year grades would be. The same students were given Expectation Tests to determine whether they thought positively or negatively. The tests also measured the way students explained the reasons for outcomes in their lives, both good and bad. Results and Discussion 7 Those who scored higher on the "positive expectation" scale were overall more successful than their peers. The Expectation Tests better predicted student success than did the formulas used by the college. Additionally, those who explained failures as being "unavoidable" were less successful than those who described the same failures as being "lessons learned."

Oklahoma Academic Standards?Grade 8 Writing Rubric

Each piece of student writing is given five analytic scores that focus on specific writing skills. These ratings range from 4 (the highest score) to 1 (the lowest score). Taken together, these scores provide a profile of the specific strengths and weaknesses of a student's writing. The following are the actual scoring rubrics used to assign the five analytic scores.

*OAS objectives are annotated for each trait. Where no specific objective is listed (i.e., 8.3.W), the whole strand is intended.
